The most significant risks that could jeopardize the success of the project is still the actual launcher mechanism, but it is not as severe as last week since we are already building it. With the 3D printed wheel attachments, 45º angle connectors and screws, PVC pipe/sheet, and putty, we are able to attach the wheels to the axis of the bike motor and use putty for stabilization and strongly attach the motor base at a 45º angle. The PVC pipe is very sturdy, which makes us feel more confident about our structure compared to the 3D printed design. A small risk would be that we are currently using temporary solutions for some parts. The PVC sheet, which acts as our base lid, did not arrive in time this week so we are using a temporary solution to attach the motors and create a distance between them to launch a tennis ball. The motor control board we borrowed from the ECE department is also not working, so a temporary one that has an on and off switch and potentiometer speed control is being used. However, these are mainly used for interim demo and once we have better working parts come in, we are confident in having everything work and integrated as intended. Pictures of current setup are included below.
No changes were made to the existing design of the system. We have updated our new schedule/ghant chart below. We are back on track with our progress after the setback from last week.
